C.O.B (Chip On Board) Nano LED, 6.5 W

Offering a hybrid spectrum and 9000K color temperature that supports fish-only marine tanks as well as plant and coral species that require lower light levels, C.O.B provides flexibility for your freshwater or saltwater nano aquarium.

Compatibility

What it is. Fluval’s Chip-On-Board (C.O.B) Nano LED packs multiple small LEDs onto one board rather than housing them as separate bulbs — the more common approach for getting light output and spectral range into a very small nano-tank fixture. This model runs a hybrid spectrum at 9000K, aimed at fish-only marine tanks plus the plant and coral species that only need lower light levels, rather than a full reef-intensity spectrum.

Where this sits in the Fluval range. The nano/desktop-format counterpart to the larger Marine 3.0 and Aquasky 2.0 fixtures — built for small and nano tanks rather than standard aquarium widths.

Setup & Use

Mounting. An over-the-glass mounting design, the same approach used on the Marine 3.0 Nano, with adjustable positioning up/down and side-to-side rather than the leg-clip mount used on Fluval’s full-size fixtures.

Build. IP67 waterproof rating, and the individual LED casts 120° of spread for even coverage across a small footprint.
